The driver page mentions an old CUDA v7.5.29, but link goes to the current version. If you already have CUDA installed, check the prefs for an update. (The last CUDA version that listed OS X 10.11.x support on the download page was CUDA 8.0.90, but the D/L page listing isn't always accurate.)

The driver page's link for CUDA goes to the latest version (CUDA 9.0.222 as of Nov. 2nd), which only lists macOS 10.13.x support. A previous CUDA 9.0.197 lists support for 10.12.x, but if you have CUDA 8.x installed, see if the prefs pane says it needs an update.
(FYI - see above for report on using CUDA 9.0.222 in macOS 10.12.6 with Security Update and new Nvidia 10.12.6 web driver.)
